Google Chrome and Windows 10 S: The new Windows 10 S operating system revealed by Microsoft is limited to running apps only from the Windows Store, and the company confirmed that users will not be able to change the default browser and machine search, which means it will only work with Edge and Bing.
This will of course be a big problem for friends of other browsers (Firefox, Chrome, etc.) because the other proletterbrowsers are not available in the Windows Store. However, it seems that even if Google were to release an app through the Windows Store, users of the new operating system would still not be able to use it. 
A publication in ZDNet reports the special requirements for browser-only Windows Store applications that a version of Google Chrome could not comply with.
"Your application must not endanger the security of users or the security or functionality of the device, system or related systems. Web browsers must use the appropriate HTML and JavaScript engines provided by the Windows platform, ”the Windows Store guidelines state.
Microsoft offers developers a set of tools with code name Project Islandwood and which make it possible to port Win32 software to UWP (Universal Windows Platform) applications.
In theory, if Google wanted to release the desktop version of Chrome in the Windows Store, it would have to use Project Islandwood tools, but according to the above requirements, the search company would need to develop the browser from the beginning using the rendering engine and JavaScript interpreters from Microsoft.
Microsoft cites security reasons for these restrictions, with a company spokesperson explaining that Edge operates in a sandbox environment to protect users from potential malware and exploits. Other browsers will have to do exactly the same (have a sandbox environment), and for that they will have to be developed from scratch using Microsoft technology.
